This is a fantasy world. It does NOT represent the real world. And even if it would, there are areas in the world with little to no variety in skin colour. Like China. Or Japan. Or Saudi-Arabia. Or South Africa. Or Norway.
Is it OK to ask for a white character in a game set in South Africa? No? Well, same applies here.
Or, in other words, if I want the Iron Hills represented from Tolkien, I want no elves or krakens there. Because that's not where those belong. That's a dwarven territory, and they ain't welcoming.
Not everything must be a melting pot, most settings aren't. Go away!
